The Notranjska Museum Postojna will be open during the May holidays from Tuesday to Sunday, between 10am and 5pm. It will be closed only on Monday, 27 April.
Visitors may explore the permanent exhibition The Karst Museum, including its extended section in the basement, as well as the new outdoor depot and lapidarium, and the temporary exhibition Crime and Fruit, which examines the phenomenon of graffiti in the Postojna area.
Foreign visitors are offered complimentary audio guides in Italian and German.
